" IMPROVEMENT IN PENS. I

Tbe Schedule referred to in these Letters Patent and making part of the same.

Be it known that I, ADnIsoN G. WATERHoUsE, of

`the city and county of San Franeisco, in the State of California, have invented a new and nseful Improve` ment ou Metallic Writing-Pens.

The nature of my `invention consists in protecting the spriugsY, by a shoulder or gauge, C, so as to pre- .vent the springs Yfrom breaking, when too great strain is put upon the pointsll.

To enable others skilled in the art to make and. use my invention, I will proceedto deseribe its construetiou and operation.

` Figure l represents lside of the pen, the slot r lr fr being so cut as toform a spring, (see letter Y, on hgs. 1, 2, 3,) between it and the point-slot K, and to lform a lever, A, and a shoulder or gauge, O. When thepoints d are sprung up by being pressed hard upon the paper, the levers A are `pressed down, so tbatthey rest on 'the shoulder or gauge C, and these preventing the springs Y from being sprung any further up than they.

can `safely bear, so as to prevent the points from being broken off.

y Figure 2 represents a top view of the pen, showing the springs Y, and part of the levers A; Figure 3' represents the pen in a at form, as it is stamped out before'being-beut into forrn, sl1owing the slots fr r that form the levers A, the shoulders or gauge C, and the springs Y.

What I- claim as my invention, and desire to secure by Letters lPatent, is-

The application of the gaugeor shoulders G, acting on the levers A, so as `to prevent too greet a strain being put upon the springs Y, and thereby preventing the points d from being broken ofi'.
